Title: Chromakey composing device
Inventor: WATANABE TOSHIROU
IPC: H04N9/75
Filed: 1980-10-15
Abstract: PURPOSE:To compose natural chromakey by introducing space filtering which generates ''blur'' in color video signals into chromakey processing. CONSTITUTION:A color video signal VA applied from an input terminal 1 is treated as the foreground signal of a panoramic photograph including chromakey back and a color video signal VB applied from an input terminal 2 is treated as a background signal for insertion. These two signals are sent to two-dimentional filter circuits 3, 4 and, after ''blur'' processing, they are inputted in a video mixing circuit 8 as a foreground signal VA' and a background signal VB' respectively. The signal VA' is also sent to a chromakey signal generating circuit 7 to generate a chromakey signal KEY with tone wedge. Thus, if the degree of ''blur'' is high, ''blur'' is generated also in the chromakey back picture at the same time as blurring of the foreground picture, so that the generated signal KEY operates as a signal with loose leading at the border of the chromakey back picture.

Title: Phase advancing condenser motor
Inventor: MIURA YOSHIHIKO
IPC: H02K17/08
Filed: 1985-07-01
Abstract: PURPOSE:To protect the switch surely even if the closed circuit is formed when the switch is turned on inadvertently, by providing intermediate taps between the main and auxiliary windings and by connecting a phase advancing condenser between these intermediate taps. CONSTITUTION:In the phase advancing condenser motor capable of controlling normal and reversible operation from outside, intermediate taps 11 and 12 are provided respectively to the main winding 2 and auxiliary winding 3. Between these taps 11 and 12 a phase advancing condenser 7 is connected. Thus, even if the other outside switch 10 is turned ON inadvertently, when one outside switch 9 is already made ON, the outside switches 9 and 10 are prevented from large current flow because there surely exists a part of a main winding and auxiliary winding in the closed circuit.

Abstract: PURPOSE:To attain the miniaturization of a magnetic disk driver by constituting simply where a collet supporter having a contact with a projected part on the rear side of a front panel through the front edge and having a collect attached at another end respectively is actuated over a cassette holder via a plate spring. CONSTITUTION:A cassette holder 3 containing a cassette can move up and down along a guide hole 13 formed on the side face of a chassis 8.

This projection 14 is put into a slit 20 of a collet supporter 17, and the supporter 17 is actuated with the slit 20 defined as a fulcrum. When no cassette is loaded, a collet 15 attached at the tip of the supporter 17 is held higher than the upper surface of the holder 3 with the slit 20 defined as a fulcrum. While the holder 3 falls when a cassette is loaded. Therefore a proper load is applied to a hub at the center of a magnetic disk from a plate spring 16 via the collet 15.

Title: Suspension device for vehicle
Inventor: KIMURA TETSUYA
IPC: B60G21/05
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain a suspension device for vehicle which improves the turning characteristic in the turning time, without reducing the straight advancing capability of a vehicle. SOLUTION: The left side and the right side carriers 1L and 1R to support the left side and the right side wheels rotatable are connected by an upper link 2 and a lower link 3 whose centers are supported rotatable and movable up and down to the car body, and the upper link 2 and the lower link 3 are made in the structure symmetrical laterally from the center to the outer side of the vehicle, and inclining in the up and down direction.  Since the upper link 2 is made in about a V-shape form inclined from the center to the upper side, and the lower link 3 is made in about a reverse V-shape form inclined from the center to the lower side, the change of the camber angle is suppressed in the same phase stroke time such as a straight advance, while the upper link 2 and the lower link 3 are rotated and the effective link length in the plan view is changed at the left side and the right side in the reverse phase such as the turning time. As a result, the turning characteristic can be improved by displacing the turning outer wheel side in a negative camber direction, as well as displacing the turning inner wheel side in the positive camber direction.

Abstract: PURPOSE:To grasp the train position by checking the train presence information, detecting a change in the train presence state, and determining a train having the top presence block section number nearest to the rear in the advance direction from the changed block section if no-presence is changed to presence. CONSTITUTION:The content of a train presence information is compared with the content immediately before, and a change of the train presence state is checked. If a change is detected, whether or not the change is caused by the advance of the top train into the next block section 2 is checked. The top presence block section number in the top block section storage region 7 of each train and the changed block section number are checked to know on which train among the trains presently registered in an advance state file 4 the change of the block section 2 occurs. The train having the nearest top presence block section number in the advance direction from the changed block section is recognized as the changed train, and the block section number is updated in the file 3.

Filed: 1983-08-09
Abstract: PURPOSE:To detect easily and quickly a fault caused in a clock oscillating section by using a couple of time constant circuits having different time constants from each other and discriminating a clock normal only when a reciprocal of a clock rate is inputted. CONSTITUTION:A D flip-flop 3, the 1st sawtooth signal generators 7-9 and the 2nd sawtooth wave signal generating sections 6, 10 and 11 are provided.

IPC: H04N13/02
Filed: 1986-06-21
Abstract: PURPOSE:To display a natural image free from flicker by outputting only one image out of right and left images outputted from a signal processing means on a finder, storing the image in a storing means and inhibiting the output of the other image. CONSTITUTION:When right image data out of a video signal K outputted from a signal processing means 38 are outputted, a field deciding circuit 41 decides an even field output period. A signal for switching to the output side from the means 38 is outputted to the multiplexer 39 and the right image data R1 are stored in a field memory 42. On the other hand, the multiplexer 39 outputs and displays the data R1 to/on the finder 44. When the left image data L1 are outputted, the circuit 41 decides an odd field output period, supplies a reading signal to the memory 42, inhibits the output from the means 38, and outputs a switching signal so that the output of the memory 42 is outputted to the finder 44. Consequently, the data L1 is inhibited and only the data R1 are applied and displayed to/on the finder 44.

Title: Power source noise detecting circuit
Inventor: FUNABASHI YOSHIHARU
IPC: H03K17/22
Filed: 1987-06-11
Abstract: PURPOSE:To eliminate a stationary penetrating current and to detect even a short-time power source noise of about several tens of ns being generated by providing a CR time constant circuit which delays variations in the potentials of the source of a 1st MOS transistor(TR) and a substrate when the power source noise is generated. CONSTITUTION:A 1st P-channel TR TP1 and a 1st N-channel TR TN1 are normally off, and a 2nd N-channel TR TN2 and a 2nd P-channel TR TN1 are off, and a node A is at a VDD potential, a node B is at a ground potential, and a node C is at a VDD potential. In this state, if the VDD potential drops by more than the gate threshold value ¦VTHF¦ of the P-channel TRs with some reason, the potential of the node A does not fall soon because of a resistance R and a capacitor C and the potentials of the source of the P-channel TR TP1 and the substrate are still the VDD potential; and only the gate potential falls, so the TR turns on. Therefore, there is no stationary penetrating current generated and the generation of even a short-time power source noise of about several tens of ns can be detected.
